Bemerkungen

  • Important Step: Strategy for CC in order to have a predictable upper distalization. We all know that the combination of distalisation + expansion is not so predictable..lets say that distalisation is a complicated movement and it requires a pure distal vector. When you combine distalisation and expansion its easy to loss track and anchorage so tracking issues can occur.
  • From UL3-UR3 AESTHETIC START MOTIVATION & UPPER RIGHT POSTERIOR IN, SIMULTANEOUSLY. From UL1-UR1-UR2 there is proclination of upper anterior in order to improve also torque of upper anterior ( when distalisation reaches upper anterior we need a correct torque of upper anterior in order to retract tem correctly).Also from U1-U13 we lingualize UR7 in order to correct the scissor bite with LR7.Four in a row means that before starting upper right distalisation we need to align UR7,UR6,UR5,UR4 in order to have a predictable pure distalisation on upper right side..
  • Retraction of upper anterior followed by intrusión of upper incisors.
  • Full time aligner+ Class II elastics wear from U13 ( start of upper right distalisation) to the end of treatment.
  • Upper right side distalisation 3.25mm in order to achieve space for a) align high erupted buccal canine b) correct class II molar and canine into class I mmolar and canine
  • Lingual conventional bite ramps at lingual of UR1,UL1 improves intrusión predictability to correct the Deep bite.
  • Important achievement: The patient only had one molar on the lower right side.Due to lower molar distalisation with invisalign technique ( 4.35mm total mm distalisation ) we achieved the space necesssary for implant placement and improve occlussion of the right side.
